Cosmic-Ray Generation by Pulsars
Physical Review Letters, 1973Electromagnetic and particle energy fluxes are equipartitioned in a superrelativistic plasma wave. The consequences for cosmic-ray acceleration by pulsars are investigated.

Generation of Radio Waves in Pulsars
Nature, 1970Pulsars generate radio waves by an unknown process which gives the highest volume emissivity known in astrophysics. The radiation forms a beam the width and polarization of which are independent of frequency. This article assembles the observational facts which any theory of emission must explain.

General Relativity Measurements from Pulsars
2020In this chapter, after a brief description of radio pulsars and their different manifestations, we illustrate the case of the so-called relativistic binary pulsars, which are fast-spinning neutron stars in orbit with a compact companion star, either a white dwarf or a second neutron star.

General relativity reveals pulsar beams
Science, 2019Radio Astronomy Pulsars are rotating neutron stars that emit beams of radio waves along their magnetic poles, seen as regular pulses if the beam points toward Earth. Desvignes et al. monitored a pulsar for more than a decade, observing how its radio pulses vary.

Pulsar Frequencies and General Relativity
Physical Review Letters, 1968The shift of pulsar frequencies due to the general-relativistic corrections to the optical path of photons in the field of the sun is discussed. Remarks concerning its detection are added.

General Relativistic Electrodynamics and Pulsar Theory
International Astronomical Union Colloquium, 1996Abstract Muslimov & Tsygan (1986, 1990, 1991, 1992) have shown how the dragging of inertial frames modifies the Goldreich-Julian charge density. The consequences are noted for different models of the electron outflow near the neutron star’s surface.

Pulsars as Next Generation Grid Timing Sources
The Precise Time and Time Interval Systems and Applications Meeting, 2021The electric grid relies on precise timing synchronization for accurate measurements, state estimation, protection and control over local, regional and national scale wide area networks. Satellite-based timing signals are used in the vast majority of these cases.

A Generic Pulsar Radio Emission Mechanism
Chinese Journal of Astronomy and Astrophysics, 2006A generic interpretation of pulsar radio emission that does not rely on the identification of a specific emission mechanism is explored. Coherence is quantified in terms of a coherence factor, which implies a maximum brightness temperature; the possible significance of Poincare invariants is pointed out, and the potential use of higher order moments of

Generation of magnetic fields in pulsars
Soviet Journal of Low Temperature Physics, 1983We consider a new mechanism of generation of magnetic fields in neutron stars, based on the superfluidity and superconductivity of neutrons and protons in the “pre” phase of a neutron star. The currents of neutron “drag” of protons results in the formation of a dense network of proton vortices around a neutron vortex.

The generation parameter and γ-ray pulsars
Chinese Astronomy and Astrophysics, 1998Abstract We have calculated the generation parameters for known γ-ray pulsars after allowing for observational effects. The calculated generation parameters show a good linear relation with the observed spectral indices. They are all numerically greater than 2.0, and we suggest that this fact can be used as a criterion for γ-ray pulsar.
